Drawings, As-built Drawings, Operation and Maintenance Manual and Records.

2.2 Definition of LOD for As-built Model

The LOD requirements are referred to the CIC Building Information Modelling

Standard. Apart from the CIC requirements, supplementary definition and

interpretation of the LOD requirements, if applicable, are listed below. The as-built

model shall follow the definition and interpretation as shown in this Guide in order to

achieve the required purpose of the as-built model in facilities upkeep.

LOD 350

CIC Building Information Modelling Standard’s Definition

The model element is graphically represented within the model as a specific

system, object, or assembly in terms of quantity, size, shape, orientation, and

interfaces with other building systems.

Interpretations in this Guide Element / object is modeled at sufficient detail and accuracy in terms of

quantity, size, shape, location, and orientation for construction coordination.

LOD 400


The model element is graphically represented within the model as a specific

system, object or assembly in terms of size, shape, location, quantity, and

orientation with detailing, fabrication, assembly, and installation information.

Interpretations in this Guide Element / object is modeled at sufficient detail and accuracy in terms of

quantity, size, shape, location, and orientation for fabrication

LOD 500


The model element is a field verified representation in terms of size, shape,

location, quantity, and orientation.

Interpretations in this Guide The existence, exact quantity, exact physical dimension, exact shape,

approximate orientation, approximate spatial location of the element / object

in the model was verified on site. Accuracy of the element / object’s setting-out

location and its spatial location should be within ± 50mm between the model

and the actual verified site installation. The 3D geometry details of the element

/ object is not less than LOD400 and the shape should be modelled for easy

identification. Essential information, such as data of fittings, manufacturer,

model number, etc. and other as specified in Appendix 1 and Appendix 3, should

be embedded in the model element / object for facilities upkeep use.




2.3 Scope of As-built Model

2.3.1 General Requirements

An accurate record of the physical conditions and assets of a project shall be provided

with reference to the requirements stated in this Guide. The as-built model using BIM

shall be based on final and verified information of the project actually built on site.

Information on location such as room number and building name, staircase number,

washroom number, lift lobby number is required to be incorporated into the as-built

model. It is necessary to include the operation data, product catalogues, O&M manuals,

maintenance history of installation and building component, etc. and other information

as required below into the as-built model.

The as-built model shall contain Room Label in 3D text object under Architectural

BIM model for labelling of all building block/ structure/ facilities in Site/ Block/ Floor

Level, etc. as required by PSB for easy identification in facilities upkeep and model

viewing.

2.3.2 Integration with ArchSD PSB’s System

Asset Information System (AIS)

The as-built model and 2D as-built record drawings including pdf shall comprise

customized building attributes and file structure for data submission in the format

approved by PSB. The as-built model and building attributes will be used for future

development on retrieval of asset and works records mapping in AIS, which is based

on a software named “ArcGIS1” by Esri.

Apart from the as-built model required in this Guide, an additional as-built model in

modified IFC version for viewing and integration with AIS should be provided. The

BIM data shall be in HK1980 Grid Coordinates System2 and refer to Hong Kong

Principal Datum. The data format shall be compatible with the IFC standard (IFC4 or

alternative advance format as requested by PSB). Coordination with PSB’s

representatives and their information technology vendor is required to further proceed

data conversion process to the submitted native BIM and IFC file for data conversion

and AIS web application by using FME 3 and GIS 4 using ArcGIS. Relevant

schedules and contract documentations stored in pre-defined folder structure shall also

be arranged to suit the file display/ downloading functions in AIS.

The IFC files produced for AIS integration shall be able to filter, screen, split or

combine to produce models for viewing with information of Site, Block and Floor

Levels. The information contained in these levels is required to be filtered suitably for

viewing and working in AIS.

1 ArcGIS is a software by Esri. The version of the ArcGIS shall be Esri ArcGIS Enterprise Standard Edition 10.4.1 or

later edition. 2 HK1980 Grid Coordinates System is a local system by Lands Department of the Government of HKSAR used in

of the FME shall be 2017 or later edition. 4 Geographic Information System is a system designed to capture, store, manipulate, analyze, manage and present spatial

or geographic data.




Level Description

Site One file for all building blocks, landscape, facilities, roads and

paths, etc. within the site boundary.

Block Separate file(s) for each individual building block, facilities and

structure, etc.

Floor Separate file(s) for each individual floor, such as basement,

mezzanine floor, cockloft, typical floors and roof, etc.

It shall be agreed with PSB if lower detailing level is preferred and accepted for display

in AIS. For projects with less complex scale and subject to PSB’s agreement, the

Site/Block/Floor levels may be provided with same IFC file(s). The original as-built

model files shall also be submitted to PSB for necessary examination and data

conversion purpose.

All contractual documentation submission shall be submitted as attachment files, i.e.

dwg, doc, docx, pdf, jpeg, jpg, xls, xlsx, mp4, etc. and other format(s) as specified/

commonly use. The submission of hyperlink for documentation retrieval from web

page is not allowed and it shall be converted to above format for storage and retrieval

in AIS.

Automated Communication Technical Information and Operations Network System

(ACTION System)

In addition, the information of the as-built model shall be modified for integration with

ACTION System, which is a property maintenance services management system of

ArchSD. The objects of the as-built model shall contain the properties as required in

Appendix 1 and one example is shown in Appendix 2. Subject to the complexity of the

project, the required properties shall be fine-tuned on request by PSB. The properties

of the objects shall be mapped with and input with the codes from the Elemental Code

Relation Table provided by the PSB in Microsoft Excel format. The table consists of

approx. 5 x 4500 numbers of parameter for elements, sub-elements, components,

attributes and remarks. As the Elemental Code Relational Table is restricted solely for

data input to the as-built model purpose, PSB shall be approached separately for

obtaining the latest version. Also, distribution of this table to third party is not allowed

without prior consent of PSB. The table may also be subject to change or amendment

without prior notification.

It is required to work with and provide at least 50 hours of technical communication
